The Iron Fists have always been hunted

In the comics, as it happens with many superheroes, there are villains who want to steal a hero's superpower. In the case of Iron Fist, one of those villains is Zhou Cheng. A martial artist himself, Cheng has hunted Iron Fists for seven decades, as a servant of a higher power.

Zhou Cheng has already been confirmed to appear in the Netflix show. However, I doubt that his character will be faithfully adapted.

And that is because, in the comics, Cheng works for a mystical beast called Ch’i-Lin, a beast who wants to feed on the dragon's heart. Unfortunately for Cheng, Danny Rand proves to be too powerful in the end, even if the villain easily defeated the current Iron Fist in their first confrontation.

To be noted, Cheng possesses another extraordinary ability: He can guess the enemy's next movement, no matter how fast it comes. So he is indeed a very powerful individual. This ability may end up being used on Netflix.
